First of all, the river is in the nomansland between a stream and a river, so it doesn't have the water volume or the power of a true river like the Susquehanna. It also widens and forms a couple of natural lakes upstream. When the water is high, lots of the excess water is pumped up and infiltrated into the esker that serves as the city's source for drinking water. There is also a small hydroelectric plant that uses the dam that was part of a flour mill up to 1963 about 7 km upstream.
Your question about the river inspired me to shoot some photos around another old flour mill that most of you will have seen before...

The water levels do vary some... the lowest level is about a meter lower than the current level and the highest about 10 cm below the hatches.
The caisson stops the stream from creating a backdraft in the mill run.

To round off for today, a smiling and singing waste bin. The vinyl wrap is a portrait of Owe Thörnquist and if there has been enough sun to charge the battery, it plays one of his songs when you press the pedal on the front to use the bin.
